SMP4-SBC-RY LED Equivalent & Substitute Parts

Part Overview

The SMP4-SBC-RY is a dual-color surface mount LED indicator manufactured by Bivar Inc., featuring independent red and yellow light-emitting elements in a 4-PLCC package. This component provides LED indication functionality with red wavelength at 631nm and yellow wavelength at 591nm, each rated at 180 millicandela with a 120° viewing angle.

The SMP4-SBC-RY is classified as obsolete. Identification of equivalent substitute parts is necessary to support ongoing production requirements, maintenance operations, and design continuity for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMP4-SBC-RY is based on strict electrical and mechanical parameter matching within the Bivar Inc. product line. The substitute part must satisfy the following criteria:

Electrical Parameters (Non-Negotiable):

• Dual red and yellow LED configuration with independent operation
• Red wavelength: 631nm
• Yellow wavelength: 591nm
• Forward voltage: 1.9V for both red and yellow elements
• Test current: 20mA for both elements
• Millicandela rating: 180mcd for both colors

Mechanical Parameters (Non-Negotiable):

• Package type: 4-PLCC
• Lens style: Round with Flat Top
• Lens size: 2.40mm diameter
• Lens transparency: Clear (colorless)
• Mounting type: Surface Mount
• Dimensions: 3.20mm L x 2.80mm W
• Viewing angle: 120°

Environmental Parameters:

• Moisture Sensitivity Level: MSL 4 (72 Hours)

The SMTL4-SBC-RY meets all specified electrical and mechanical parameters and is therefore classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The SMTL4-SBC-RY is the direct parametric equivalent for the obsolete SMP4-SBC-RY. Selection of the SMTL4-SBC-RY is based on the following factors:

Product Status: The SMTL4-SBC-RY maintains active product status with Bivar Inc., ensuring ongoing availability and manufacturing support. The SMP4-SBC-RY is classified as obsolete and is no longer in active production.

Electrical Equivalence: All electrical parameters are identical, including forward voltage, test current, wavelength specifications, and millicandela ratings for both red and yellow elements.

Mechanical Equivalence: Package type, dimensions, lens specifications, and mounting configuration are identical between the two parts.

Environmental Compliance: The SMTL4-SBC-RY is ROHS3 compliant and REACH unaffected, providing enhanced regulatory compliance compared to the obsolete SMP4-SBC-RY.

Physical Tolerance: The maximum height specification differs by 0.10mm (1.95mm versus 2.05mm), which remains within standard PCB assembly tolerances for surface mount components.

Packaging Availability: The SMTL4-SBC-RY is available in Tape & Reel (TR) packaging format, supporting automated assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the SMTL4-SBC-RY be used as a direct replacement for the SMP4-SBC-RY in existing designs?

A: Yes. The SMTL4-SBC-RY is a parametric equivalent with identical electrical and mechanical specifications. All critical parameters including forward voltage, test current, wavelength, millicandela rating, package type, and dimensions are matched.

Q: What is the significance of the 0.10mm height difference between the two parts?

A: The SMP4-SBC-RY has a maximum height of 1.95mm, while the SMTL4-SBC-RY has a maximum height of 2.05mm. This 0.10mm difference is within standard PCB assembly tolerances for surface mount components and does not affect functional compatibility or PCB layout requirements.

Q: Why is the SMP4-SBC-RY classified as obsolete?

A: The SMP4-SBC-RY is no longer in active production by Bivar Inc. The SMTL4-SBC-RY is the active equivalent product that replaces it in the manufacturer's current product line.

Q: Are there any compliance differences between the two parts?

A: The SMTL4-SBC-RY is ROHS3 compliant and REACH unaffected. Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: What packaging formats are available for the SMTL4-SBC-RY?

A: The SMTL4-SBC-RY is supplied in Tape & Reel (TR) packaging, which is standard for automated surface mount assembly operations.

Q: Are the electrical characteristics identical between the SMP4-SBC-RY and SMTL4-SBC-RY?

A: Yes. Both parts feature identical forward voltage (1.9V for red and yellow), test current (20mA for red and yellow), wavelength specifications (631nm red, 591nm yellow), and millicandela ratings (180mcd for both colors).

Q: Can the SMTL4-SBC-RY be used in applications requiring the SMP4-SBC-RY's specific packaging format?

A: The SMTL4-SBC-RY is available in Tape & Reel format. If the original application required a different packaging format, the Tape & Reel format is compatible with standard automated assembly equipment.
